预应力钢筋混凝土工程中使用大量的锚具——锚塞和锚环,都要做探伤检验。实践表明,锚环的裂纹问题比锚塞的多一些。这样就提出了一个问题:带有裂纹的锚环还能否使用,有何根据? 对此,目前的施工验收规范未作硬性的规定。显然,若限制过严,以为一经探伤发现裂纹便不许使用,则会造成 In the prestressed reinforced concrete project, a large number of anchorages—anchors and anchor rings—are used for flaw detection. Practice shows that the crack problem of the anchor ring is more than that of the anchor plug. This raises the question of whether or not the cracked anchor ring can be used. What is the basis for this? The current construction acceptance code has not been rigidly stipulated. Obviously, if the restriction is too strict, it is thought that cracks will not be used if cracks are detected.
